在另一个LinearGradientBrush中使用LinearGradientBrush？ [英] Use a LinearGradientBrush in another LinearGradientBrush?

问题描述

我想在另一个LinearGradientBrush的定义中使用一个LinearGradientBrush。但我不知道天气这甚至可以工作，如果它的工作，我需要知道如何。

I'm trying to use one LinearGradientBrush in the Definition of another LinearGradientBrush. But I've no idea weather this would even work, and if it works, I need to know how.

例如：

    <LinearGradientBrush x:Key="ComboBoxFocusBackgroundBrush" EndPoint="0.5,1" StartPoint="0.5,0">
        <GradientStop Color="#FFFDEEB3" Offset="0"/>
        <GradientStop Color="#FFFBF2CD" Offset="1"/>
        <GradientStop Color="#FFFCE48A" Offset="0.5"/>
        <GradientStop Color="#FFFBE388" Offset="0.75"/>
    </LinearGradientBrush>

    <LinearGradientBrush x:Key="FilterPopupTitleBrush" EndPoint="0.5,1" StartPoint="0.5,0">
        <GradientStop Color="#B45988" Offset="0.75"/>
        //Code here to use ComboBoxFocusBackgroundBrush
        <GradientStop Color="#990088" Offset="0.75"/>
    </LinearGradientBrush>

感谢您预期答案

编辑：
为了使事情更清楚在示例中我想使用FilterPopupTitleBrush中的ComboBoxFocusBackgroundBrush作为一个模板。因为我有两个画笔没有副本相同的颜色渐变的< GradientStop ...>标签

To get things a bit more clear in the example I want to use "ComboBoxFocusBackgroundBrush" in the "FilterPopupTitleBrush" as a "template".So that I've the same color gradient in both brushes without a copy of the "<GradientStop...>"-tags

推荐答案

您可以共享多个画笔之间的渐变停留列表，像这样： -

You can share the list of gradient stops between multiple brushes, like this:-

<GradientStopCollection x:Key="MyGradient">
    <GradientStop Color="#FFFDEEB3" Offset="0"/> 
    <GradientStop Color="#FFFBF2CD" Offset="1"/> 
    <GradientStop Color="#FFFCE48A" Offset="0.5"/> 
    <GradientStop Color="#FFFBE388" Offset="0.75"/> 
</LinearGradientBrush> 

<LinearGradientBrush x:Key="ComboBoxFocusBackgroundBrush" EndPoint="0.5,1" StartPoint="0.5,0"
   GradientStops="StaticResource MyGradient}" /> 

<LinearGradientBrush x:Key="FilterPopupTitleBrush" EndPoint="0.5,1" StartPoint="0.5,0"
    GradientStops="{StaticResource MyGradient}" /> 

现在您可以改变 EndPoint code> StartPoint 和其他属性创建相同基本渐变的不同变体。

Now you can vary the EndPoint, StartPoint and other properties create different variants of the same basic gradient.

你甚至可以提供相同的集合到 RadialGradientBrush 。

You can even supply the same set to RadialGradientBrush.
